IEC PW-33-Y porcelain pin type insulators are the international standard ceramic pin insulator or distribution pin insulator, which can be used on cable pole line and consist of insulator pin and zinc sleeve.

IEC PW-33-Y porcelain pin type insulators laboratory and research facilities:
Material science is present at every angle of distribution pin insulator or ceramic insulators technology. Beyond more traditional mechanical and electrical testing facilities for which Orient Power has full testing equipment available either in the factory laboratories or, at a larger scale, in our Research Centre in China, Orient Power has also implemented state of the art material testing capabilities. Orient Power does all set of IEC PW-33-Y porcelain pin type insulator in our independent laboratory.

IEC PW-33-Y porcelain pin type insulators/distribution pin insulator structure:
The main material of general IEC PW-33-Y porcelain pin type insulators for iron cap, ceramic and steel feet, and combined with cement glue is an integral whole. Pin insulator has another two type insulators which are toughened glass pin insulator and composite pin insulators. Neck type of distribution pin insulator can be C-neck，F-neck，K-neck，J-neck and neck diameter of porcelain pin insulators can be 57mm, 78mm, 89mm, 102mm.
